Abstract
PROCEDIMIENTO Y DISPOSITIVO PARA ELIMINAR OXIDOS DE NITROGRENO (NOX) DE GASES DE ESCAPE, EN DONDE EL PROCEDIMIENTO CONSISTE EN SOMETER ESTOS GASES, MEZCLADOS CON AMONIACO, A REDUCCION CATALITICA A TEMPERATURAS DE HASTA 300JC DE TAL MODO QUE EL TIEMPO DE PERMANENCIA CONJUNTO DEL GAS DE ESCAPE Y EL AMONIACO ANTES DE SU CONTACTO CON EL CATALIZADOR SEA COMO MAXIMO ANTES DE SU CONTACTO CON EL CATALIZADOR SEA COMO MAXIMO DEL SEGUNDO. EL DISPOSITIVO COMPRENDE UNA CONDUCCION (2) QUE LLEVA DICHOS GASES DE ESCAPE Y CONTIENE UN CATALIZADOR (3), ASI COMO UNA ALIMENTACION (4, 1) PARA AMONIACO QUE ESTA PROVISTA DE MEDIOS DE INYECCION (6) DISPUESTOS DELANTE DE LA SUPERFICIE FRONTAL (7) DEL CATALIZADOR. EL INVENTO ES APLICABLE A LA DEPURACION DE GASES DE ESCAPE PROCEDENTES DE CENTRALES PRODUCTORAS DE ENERGIA QUE QUEMAN COMBUSTIBLES QUE CONTIENEN NITROGENO, ASI COMO DE INSTALACIONES PARA FABRICAR ACIDO NITRICO.
